-My invention relates to paper feeding mechanisms for type-writers,calculating machines, tabulating machines and the like. Moreparticularly the invention relatesto a paper feeding mechanism by meansof which the text, numbers and the like to be written may quickly bedistributed over any desired portions of a long paper band.

- All oflice appliances provided with means for type-writing, except thebook-typewriters, involve the introduction of the socalled loose leaves,if they are to be used for bookkeeping and similar purposes. That is tosay, a particular leaf is used for each account and the whole collectionof uniform leaves takes the place of bound books.

The disadvantage of suchan arrangement is first that loose leaves mayeasily be misplaced, become lost and the like and second that a greatamount of time is lost in intro-.

ducing the single leaves into the machine.

The object of the present invention is to provide a device which securesthe advantages inherent in a bound book as well as .25 those whichresult from the use of loose leaves. To obtain this, the loose leavesare replaced by a single long paper band or web, the ends of which areconnected to and wound upon rollers which may be rotated by hand or by amotor in such a manner that the paper is wound upon the one and unwoundfrom the other roller or vice versa. If, for instance, such ardeviceisto be used for keeping the balance account and if there are aboutlOOaccounts, the account headings would be marked upon a paper band or webof about 50 m. length and of a width corresponding to the widthof theplaten of the machine 'in question in such a manner that a space ofabout 50 cm. remains between each two consecutive account headings. Eachof these sections of a length of 50 cm. corresponds to an account lea ofa loose leave book or to a page of the balance account book;

In the accompanying drawing a machine according to the invention isshown by way of example. I

Fig. 1 is a perspective view and Fig. 2 shows a diagrammatic side-view,

The web or band 1 of paper which is wound upon the roller 2 is passedover and in surface engagement with the roller 3, which may representthe platen of a typewriting machine (Fi 2) and then around the spindle 4(Fig. 1 of the roller 5 where it is clamped by means of a resilient rail7 against a longitudinal notch 6 of the spindle 4. To now move the stripor band 1 to the desired section (account or the like), the key 8 isdepressed, whereby a circuit across the driving motor 9 and amagnet-clutch 10 is closed. The'clutch 10, arranged upon the drivenaxle-arm 11 in a manner to be displaceable thereon in a longitudinaldirection I but secured against relative rotation, is moved, against thetension of a spring 13, towards the counter piece 14 as soon as thecircuit across the winding 12 is closed. As the counter piece ll'isconnected to a flange 7 15 which is secured against relative rotation,and is pressed, by means of a spring 16, against the paper roller 5 andengages this roller by a pin 17, the roller 5 now starts to rotate withthe. speed of the drive. As

soon as the desired portion of the strip or band 1 visibly appears, themovement of the rollers is interrupted by relieving the pressureupon'the key 8. The final adjustment to the desired line is theneffected by manually rotating a turn-button 18 connected to a pin 19which extends into the paper roller and is secured against relativerotation by means of a pin 20.

' If the strip or band 1 is to be moved in the 3.5.

opposite direction, the key 21 is depressed. This causes closing of acircuit across the clutch 22 of the roller 2 which acts in exactly thesame manner as the clutch 10. The roller 2 also is provided with aturn-button 23 to manually effect the fine adjustment. To exchange andto replace the paper rollers, both are simultaneously pressed againstthe flanges 15, whereby the springs 16 are compressed and the rollersmay be lifted from the pins 19.

The force of the clutch magnets 10 and 22 is so chosen, that at firstthe clutches slip fa little on the counter pieces 14 so that a suddencoupling is prevented which would of easily and quickly brlnglng, aboutthese cause breaking of the paper strip 1. The springs 16 on the otherhand are so tensioned, that theunwinding roller is braked in such amanner as to always keep the paper strip 1 perfectly tightened.

n practice it is ofttimes necessary, in passing from'one account toanother, to shift the web of' paper 1 for a distance of 10 or .m. byunwinding it from one roller and winding itupon the other. For thepurpose relatively large operations of the paper web 1, the aforesaiddriving or operating means. for the paper rollers 2 and 5 are pr0-.

.vided.' Besides such driving means for rapidly operating the rollers,.aconventional switching the said motor in circuit with one or the otherof the two electro-magnetic clutches to drive the roller of theclutchwhich is energized.

In testimony' whereof I have aflixed my signature.
